“I bought these KSC75 clips because I lost my modded Koss UR55 and I read oodles of praise for them online. At first I was skeptical because they are very flimsy looking and they are often compared to the Koss PortaPro which sounds muddy in my opinion. So I tried them on and I was immediately impressed by the overall balance and airy sound. Everything sounds so natural and forward, and...” --kokakolia

What can be said about these headphones that has not already been said in the 25+ years they have been in production?
Well, my girlfriend thinks they look silly... And that for some odd reason makes me love them more.
Out of few phones I currently own, I always find myself reaching for these.
With the wonderful bass and full bodied sound comes the...” --BloodyPenguin

“
I've tried about two dozen pairs of headphones and I'm always looking for the absolute best pair for vocals. I also want forward sounding mids, but not too bad. My preference is also for highs that are not harsh or fatiguing. Being somewhat rolled off is ok. I find the SRH-840 is what I like in this area.
The best thing about this headphone is the quality of vocals. It just sounds...” --tdockweiler

“wow! am i really the first to write a review for the venerable portapro??
the portapro is an age old design, but has held up over the years, despite newer portable cans coming along. and perhaps it is the very age of the design that keeps people coming back to it. what with its alnico magnets and paper diaphrams. and it's weird retro look. and its mega fun sound!!!
yep, the sound is...” --TheWuss

“***UPDATES WILL COME AFTER SEVERAL DAYS OF BURN-IN***
I recently ordered the Koss Pro4s and PortaPros to add to my collection. Both of them arrived today (3 days for shipping) and immediately I ran into some quite difficult packaging. The covering over the box had been glued to the box, making it extremely difficult to preserve the outer covering when trying to open it. After...” --ODDEEO

“
Another Head-Fier here helped me get a pair of these from the Koss outlet store recently. On day one I didn't like them at all. Had this very weird and unbalanced sound signature. When using them with games it's very noticeable where it's focus is. After day one I found they just had too little bass and way too much treble for me. Tried them later and had the same impression.
I...” --tdockweiler

Koss UR 55 Studio Pulse An inexpensive performer
There's a vast array of inexpensive headphones out there. Thousands of them. But every now and then, if you sample around, much like wine, you can fine something inexpensive that is actually pretty good. The Koss UR 55 Studio Pulse is a headphone that fits that description. I picked it up for $35 from Amazon (was on sale, goes on...” --MalVeauX

PRO DJ100/200 REVIEW
First review on Head-Fi! Yay! Please forgive me if my description isn't as techie as some others from more serious audiophiles and, because I'm from Germany, please forgive mistakes I make in this English text.
I currently own a Grado SR 325, Grado SR 125 (actually my girlfriends), the obvious Porta Pros and now the Koss DJ200 and I can compare...” --Electonic

“I tested it with Dr.Chesky's Binaural album and Depeche Mode flacs. What I like most is of course bass response..it is more than enough, maybe a bit exaggerated, aggressive. Overall, I am really satisfied this excessive response in some genres.The only real problem it is prone to loudness noise of the record.. Maybe this is because the drivers are too sensitive. I am not that high end...” --ajlan

To make this easier to read I'm going to break it up the review into a few different categories: build quality & design, accessories, comfort, and sound. But first:
Build Quality & Design: 4.5/5
When I first open these up I was struck by how good looking they are. They have a nice shine to the black cups, and although...” --hipster2010
